Sandro Tonali paid off the first instalment of his €60million transfer fee as he marked a fine debut with his first goal and inspired Newcastle to a 5-1 drubbing of Aston Villa. The 23-year-old Italy international opened the scoring just six minutes into his first competitive appearance for the Magpies and had a hand in two more of their goals as Alexander Isak helped himself to a double and substitutes Callum Wilson and Harvey Barnes struck late on after Moussa Diaby, also making his bow in England's top flight, had levelled.
